...bullet, far faster than any earthbound man had ever traveled before. At the end of the run the sled went down from 632 m.p.h. to a dead stop in 1.4 seconds. As the sled decelerated, Colonel Stapp was subjected to more than 40 times the pull of gravity (40 gs); his normal weight of 168 ½ lbs. momentarily shot up to 6,740 lbs. The driver of an ordinary automobile colliding with a brick wall at 50 m.p.h. would be taking much the same jolt-yet Stapp survived it with negligible injuries...
Aircraft designers, forever increasing the capabilities of their planes, must constantly make expensive compromises to take care of the pilot. Until Medico Stapp came along with his cool scientist's insistence on using himself as guinea pig, fighter-planes were built to stand an expected stress of nine gs. It hardly seemed worth while to make them stronger. The human body, the engineers insisted (and most doctors believed), could not take greater physical strain. Not the machine but man himself appeared to be limiting man's conquest of the jet age. However the engineers tried, they could...
...Colonel Stapp had himself taken 16 rides and had been subjected to g stresses up to 35 times the pull of gravity. Slowly, the impressive statistics were piling up. "The men at the mahogany desks," says Stapp, "thought that the human body would never take more than 18 gs. Here we were, taking double that-with no sweat...
...Mach 1 is the speed of sound: 760 m.p.h. at sea level, 660 m.p.h. at 35,332 ft. (beginning of the stratosphere) and above. †50 gs for ¼ of a second, building up at a rate of 500 gs per second; 40 gs for 1/5 of a second, building up at 1,500 gs per second; 25 gs for one second; building up at 600 gs per second. * One of them: "Siberian Tiger Steak." Recipe: "Take a one-vertebra thickness of Tbone, rub with sodium glutamate, powdered ginger, powdered mustard, garlic, thyme and cumin seed before broiling...
Outside Loop. Airmen learned years ago that the pull of positive Gs can cause blackout because it drives the blood from the head down into the body (TIME...
